The invention consists in a, novel externally threaded divided glandand-inthe com-- bination therewith of a receivingsocketinto,

which it is screwed'and a flanged-out pipe or tube clamped by the gland,and-in the novel construction of parts as hereinafter more.

Referring to the drawings, the simplest form of my improved pipeconnection or that in which'a pipe or tube is connected to a stationaryart, as the steam chest of an engine, is s iown to comprise thestationary part A, having an aperture b and a screw threaded recess (1enlarged therefrom to provide an annular seat. or shoulder e around theaperture, and an externally threaded divided gland 'i i screwed into therecess and embracin a pipe or'tube F having a flanged out end betweentheseat and the end of the ring, as viewed in cross section in Fig. 4.

I Specification ofLetters Pate nt Patented April 27, 1909.

' The gland is. provided with .a flange i which is ofhexagonalperimeter, as shown in Figs. 2 andvfi, orotherwise adapted fortheapplicationof a wrench to screw the gland into the recess of thestationary part; The gland may be divided into any required number ofsections, but ordinarily preferably com )rises twoequal parts or halvesi andt, as s own in Figs. 2, 5, (Sand 7.

The two halves of the divided gland are held .in proper. relation toeach other or with their respective screw threads coincident by means ofthe .following construction. On

oneside of the gland, at the plane of the joint thereof, the res )ectivehalves are provided with a longitudinal intermeshing tongue 9 andcorrcspomlinggrooves g which cil'cc-v tually prevent lateral play of theparts on eachother... On the opposite side the sec tions are,respectively, provided with a series of transverse teeth It andcorresponding notches h wl'uch, by being mtermeshed togethenpreventlongitudinal motion of the parts re atively to each other. Thus fittedtogether, the parts of the gland may in operation be placed upon a,.pipeor tube and as readily entered and screwed into the recess d of the artA as if made in one piece or solid ring. his tongue and roove andnotched construction of the two lalves of the gland may be dispensedwith without departing from the spirit of my invention, but it will beseen that, when the halves are made plain and unconnected, great carewill need to be exercised to locate them properly in assembling theparts. By unscrewing the gland from the recess its parts may e removedfrom the pipe and the pipe detached from the part A, or turned in itsseat for the purpose of removal from another ipe or part.

. The invention in the orm in which it is adapted as a pipe union forcoupling two pipes or tubes together is shownpartlcularly in Figs. 1 to'3, inclusive. In this modification the element which corresponds to thestationary part A com rises, a collar or socket A otherwise of t econstruction involved in said part A, that is, havin an aperture andthreaded recess enlar therefrom providing an annular shonl or or seataround the aperture at the bottom of the recess. The socket is ofhexagonal perimeter or otherwise adapted for the apfplication of awrench, andfit embraces one o the pipes F which are to be coupled toether, and which is provided with an externa flange f 8 adapted toimpinge upon the seat or shoulder e of the socket A requires to beplaced upon the pipe before making up the line of piping. and it' cannot then be removed therefrom without detaching the opposite end ofthe pipe from the art to'which it is connected. it is desirable in someinstances that all the elements of the union shall be removable from thepipes and this result may readily be accomp ished by forming the seat atthe bottom of the socket I by means of a divided'gland screwed into theconnected from collar from that end, as shown in the constructionillustrated in Fig. 10. The collar A in such case is of a substantiallyuniform diameter throughout of suflicient size to receive the flanges f2 f 3 .of the pipes F and internally screw threaded from each end. A-

divided gland it is then screwed into each end of the collar, thus claming the flanges of the pipes between them. Vhen the divided glands areremoved, the collar may be disends apart suflicient y to pass it betweenthem. I j

In the form of the invention adapted for -connecting a pipe or tube withan engine ora tank or other rece tacle, a modification may be employedwhic operates essentially as an expansion joint. In this construction,which ar shoulder e of the socket. In the form of union above described,the

the ipes by forcing theiris shown in Fi 11, the pipe H is not providedwith a ange at its end, but is left straight, and rejected into theaperture 1) in the tank or ed part A for some distance beyond the bottomof therecess d or shoulder thereof. The divided gland "i i is )lacedupon the ipe in the manner herein efore described, ut. a suitable ringof elastic packing m is placed between its end and the shoulder e in therecess (1 and firmly compressed upon the pipe by being clamped betweenthe parts. This construction also provides an excellent union whichallows expansion and contraction of the line of piping.

The flexible feature referred to in the expansion joint above describedadapts this construction for general stuffing box use, as it willreadily be perceived that it is but a stufling box with a divided gland.

I claim as my invention:

In pipe connections, the combination of a socket and a longitudinallydivided gland having its respective parts rovided with longitudinalinterlocking shouiilers or engaging surfaces on their meeting edges atone side of the axis and transverse interlocking serrations at the'rmeeting edges on the oposite side, wh :eby both transverse and engthwisedisplacement of'the parts relative to each other 1s prevented.
